This parameter controls xGMI p2p communication, which is enabled by default. However, it can be disabled by setting it to 0. In case xGMI p2p is disabled in a dGPU, PCIe p2p interface will be used instead. This parameter is ignored in GPUs that do not support xGMI p2p configuration. Signed-off-by:

[Why] Detbuffer size is dynamically set for dcn31x. At certain moment, compbuf+(def size * num pipes) > config return buffer size causing flickering. This is easily reproducible when MPO is enabled with two displays. [How] At prepare BW, use the min comp buffer size. When it is to optimize BW, set compbuf size back to maximum possible size.

Workstation application ANSA/META v21.1.4 get this error dmesg when running CI test suite provided by ANSA/META: [drm:amdgpu_gem_va_ioctl [amdgpu]] *ERROR* Couldn't update BO_VA (-16) This is caused by: 1. create a 256MB buffer in invisible VRAM 2. CPU map the buffer and access it causes vm_fault and try to move it to visible VRAM 3. force visible VRAM space and traverse all VRAM bos to check if evicting this bo is valuable 4. when checking a VM bo (in invisible VRAM), amdgpu_vm_evictable() will set amdgpu_vm->evicting, but latter due to not in visible VRAM, won't really evict it so not add it to amdgpu_vm->evicted 5. before next CS to clear the amdgpu_vm->evicting, user VM ops ioctl will pass amdgpu_vm_ready() (check amdgpu_vm->evicted) but fail in amdgpu_vm_bo_update_mapping() (check amdgpu_vm->evicting) and get this error log This error won't affect functionality as next CS will finish the waiting VM ops. But we'd better clear the error log by checking the amdgpu_vm->evicting flag in amdgpu_vm_ready() to stop calling amdgpu_vm_bo_update_mapping() later. Another reason is amdgpu_vm->evicted list holds all BOs (both user buffer and page table), but only page table BOs' eviction prevent VM ops. amdgpu_vm->evicting flag is set only for page table BOs, so we should use evicting flag instead of evicted list in amdgpu_vm_ready(). The side effect of this change is: previously blocked VM op (user buffer in "evicted" list but no page table in it) gets done immediately. v2: update commit comments. Acked-by:

[Why] When hotplug or unplug happens, each stream disabled one by one, and then enable any alived streams. Link phy and payload table is cleared when 1st stream is disabled. That causes the error message pops up when disable 2nd stream. There is no active stream after link_rate is cleared. After all streams are disabled, link will be trained again and link rate is assigned to any alived streams. Therefore there is no harm for the error message that represents invalid link rate value in the atomic reset transitional time period. [How] Downgrade the log level from ERROR to DEBUG. Reviewed-by:

[Why] Hotplugging the VGA side of some DP/VGA adapters caused the display to light up with the wrong (non-native) resolution. This is caused by the adapter misbehaving by reporting the wrong number of downstream ports when the VGA side is unplugged (reports 1 instead of 0), but only if the SINK_COUNT DPCD register is read more than once. [How] To work around the adapter behavior, remove the sink if link is detected, but EDID cannot be read. Reviewed-by:
